The amazing Microsoft Telescope Web Interface adds simplicity and functionality to the wow-ness of the original. It’s powered by Silverlight – which for the sneering classes, is starting to power some pretty cool stuff like the video on demand services of Sky – which works really well as a streaming technology! How cool is this…? Well try a zoom in from a space view of earth…

…to a view of the East Village in New York. Totally amazing.

There are some great tours as well, complete with music and stupendous Virtual Earth-scapes.
